Question

我想将RF24库嵌入docker映像中。为此，我在Dockerfile中添加了以下语句：

FROM arm32v7/node:10

RUN mkdir -p /home/node
WORKDIR /home/node

COPY package*.json ./

USER root

RUN apt-get update -y && apt-get install -y sudo git

RUN git clone https://github.com/nRF24/RF24.git
RUN cd RF24 && make && sudo make install

RUN npm install

EXPOSE 3000
CMD ["npm","start"]

但是，当我在Raspberry pi3上执行docker构建时，我注意到发生以下错误。

[Running configure]

奇怪的是，我没有使用Docker，
当我直接在bash shell中键入命令时，会得到不同的结果

输入如下

cd ~
git clone https://github.com/nRF24/RF24.git
cd RF24 && make && sudo make install

这是结果

我对这个结果感到困惑。有人请帮助我。
